Heatkeeper Installation Instructions
HEATKEEPER® Radiator Reflector Panels — Installation Guide
Heatkeeper panels have been specially designed to be easy to fit without removing your radiator. The panels are sized to suit the most common household radiators in the UK, with built-in cutting divisions and scissor lines to make adapting to different radiator dimensions straightforward.
Choosing the Right Panel Size
Use the table below to select the correct panel sections for your radiator height:
| Radiator Height (mm) | Use Section Numbers | Panel Height (mm) |
|---|---|---|
| 300 | 2+3 | 260 |
| 400 | 1+2+3 | 375 |
| 450 | 3+4 | 410 |
| 500 | 2+3+4 | 465 |
Illustrated, easy-to-follow fitting instructions are included in every pack along with industrial-standard self-adhesive fixing tape.
Method 1: Secure Taping the Panels
This is the standard fitting method, suitable for most radiators.
Heatkeeper Reflector Panels are designed to be fixed directly to the wall behind the radiator using the self-adhesive tape supplied. The size and shape of the panel is designed to suit the most common household radiators in the UK. Cutting divisions and scissor lines make it easy to adapt the panel to varying radiator dimensions.
Method 2: Hanging the Panels
For hard-to-reach areas, use the NEW Easy-Fit hanging method. Simply hang Heatkeeper panels from your radiator brackets — ideal for radiators hung close to the wall or under an overhanging window sill.
This method uses DURAGRIP spines, which fit securely along the top of the panel and hook over the radiator brackets.
How many spines will I need?
DURAGRIP spines are 300mm long (A4 size) and 3mm deep. It takes 2–2½ Heatkeeper panels to fit an average 1000mm radiator, so you will need approximately 3 spines per 1000mm radiator, covering the areas between and either side of the brackets. Spines can be cut to fit, just like the panels themselves.
